# Getting Started

Discover scans your data sources and applies relevant tags when data is recognized. This eliminates a manual tagging process for your data, saving you time and providing standard taxonomy across all your data sources.

## Requirements

* SDD enabled and [turned on](https://documentation.immuta.com/2024.2/application-settings/how-to-guides/config-builder-guide#enable-sensitive-data-discovery)
* [Frameworks enabled](https://documentation.immuta.com/2024.2/application-settings/how-to-guides/config-builder-guide#enable-discover-features)
* Registered [Snowflake, Databricks, Redshift, or Starburst (Trino) data sources](https://documentation.immuta.com/2024.2/data-and-integrations/registering-metadata/register-data-sources/query-backed-tutorial)
* Immuta permission `GOVERNANCE`

## Implement SDD

Sensitive data discovery (SDD) is an Immuta Discover feature that scans your data sources and applies relevant tags when data is recognized. This eliminates a manual tagging process for your data, saving you time and providing standard taxonomy across all your data sources.

To learn more, see the [Data discovery page](https://documentation.immuta.com/2024.2/discover-your-data/data-discovery).

### Enable sensitive data discovery

Enable sensitive data discovery to start using the default framework on all of your registered data sources. This out-of-the-box framework discovers common data types and tags them automatically when a new data source is registered.

1. [Turn on SDD](https://documentation.immuta.com/2024.2/discover-your-data/data-discovery/how-to-guides/enable-sdd)
2. [Trigger SDD on a data source](https://documentation.immuta.com/2024.2/data-discovery/how-to-guides/manage-sdd-tags#run-sdd-on-a-data-source)

### Configure SDD for your data

For additional control, create your own patterns to recognize the data that matters to you. Add these patterns to new frameworks and specify the data sources that need this framework. This fine-level control creates automatic tagging that is relevant and accurate to your data, requiring fewer manual adjustments to the resulting tags.

1. Customize SDD for your data:
   1. [Create patterns](https://documentation.immuta.com/2024.2/data-discovery/how-to-guides/manage-patterns#create-a-pattern)
   2. [Create a framework](https://documentation.immuta.com/2024.2/data-discovery/how-to-guides/manage-frameworks#create-a-framework)
   3. [Create rules](https://documentation.immuta.com/2024.2/data-discovery/how-to-guides/manage-rules#create-a-rule)
2. [Assign your framework to specific data sources](https://documentation.immuta.com/2024.2/data-discovery/how-to-guides/manage-frameworks#assign-a-framework-to-data-sources)

### Adjust Discovered tags

If you have any tags that are applied to your data sources by SDD that you don't want, you can easily disable these tags for each data source. This ensures that they will not be applied to the data source again if SDD is re-run.

1. [Verify tags](https://documentation.immuta.com/2024.2/data-discovery/how-to-guides/manage-sdd-tags#verify-discovered-tags)
2. [Disable Discovered tags](https://documentation.immuta.com/2024.2/data-discovery/how-to-guides/manage-sdd-tags#disable-discovered-tags-from-the-data-dictionary)

**Reference pages**:

Immuta comes with a default framework containing built-in Discovered tags and built-in patterns. These patterns and tags can be used in your own frameworks.

2. [Built-in patterns](https://documentation.immuta.com/2024.2/discover-your-data/data-discovery/reference-guides/classifier-reference)

## Implement classification

Classification is an Immuta Discover feature that categorizes your data based on the content and the associated risk the data poses. This increases your understanding of your data and allows you to make faster decisions about it.

### Enable classification

[Enable classification from the Immuta app settings page](https://documentation.immuta.com/2024.2/application-settings/how-to-guides/config-builder-guide#enable-discover-features).

### Activate a framework

Activate any of the following frameworks:

* To start seeing classification tags, enable the [Data Security Framework](https://documentation.immuta.com/2024.2/data-classification/immuta-frameworks#data-security-framework).
* If you are using Snowflake and want to see information on your sensitive data in Detect, enable the [Risk Assessment Framework](https://documentation.immuta.com/2024.2/data-classification/immuta-frameworks#risk-assessment-framework).
* Opt to enable any of the other [compliance frameworks](https://documentation.immuta.com/2024.2/data-classification/immuta-frameworks#compliance-frameworks).

Complete the following steps for each framework you want to activate:

1. Navigate to **Discover** and select the **Classification** tab.
2. Click the **more actions** icon in the Actions column for the framework you want to activate.
3. Select **Activate**.

### Configure classification for your data

To configure or manage a framework using [the Immuta API](https://documentation.immuta.com/2024.2/developer-guides/api-intro/immuta-v1-api/authentication), see the [Frameworks API reference page](https://documentation.immuta.com/2024.2/developer-guides/api-intro/immuta-v1-api/configure-your-instance-of-immuta/frameworks).

### Adjust classification tags

If you have any tags that are applied to your data sources by classification that you don't want, you can easily disable these tags for each data source. This ensures that they will not be applied to the data source again when classification is re-run.

1. [Assess your data source tags](https://documentation.immuta.com/2024.2/data-classification/how-to-guides/adjust-classification-tags#assess-your-data-source-tags).
2. [Tune your data dictionaries](https://documentation.immuta.com/2024.2/data-classification/how-to-guides/adjust-classification-tags#tune-your-data-dictionaries).
